Abstract: A multi-unit data-collecting/information-generating/instruction-passing/communication-n etwork being a multiplicity of individual microprocessor systems capable of data-collection/presenatation/order-passing associated with instrumentation, process control elements and/or information displays, indicators and recorders on a two or three wire network programmed in a manner to enable(1) each individual information generating system comprised of one data measuring instrument generating a signal connected in juxta-position to an A/D and a microprocessor capable of converting analog signals from the instrumentation to digital signals then to serial digital strings and through a transceiver (T/R) transmit said digital serial strings onto the network,(2) each individual information-passing system comprised of a T/R-microprocessor-A/D juxta-positioned with a process control element, said system capable of recognizing an identifier code within a serial digital string containing instructions for said process control ele
